Application filed April 18, 1907. Serial No. 868,863.

T all whom it may concern:

Be it known that l, FRED SALINGER, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented a certain new and useful Adding-Machine, of which the followingis a specification.

The object of my invention is to provide an adding machine that willprint the nu1n bers in properly arranged columns, and that may easilyand quickly be operated to print the totals of the numbers at anydesirable time, and that may be-shifted to bring all of the addingwheels back to starting posi- 5 tion, and that will. visibly indicate tothe operator the position of each adding wheel at all't'nnes.

My object is primarily to provide a machine of' 'this kind of simple,durable and inexpensfve construction.

My inventlon consists 1n certain details in the construction,arrangement'and coinbination of the various parts of the device wherebysimplicity and durability of con,

struction are provided, and at the same time a machine is producedcapable of accomplishing all of the desirable results of the morecomplicated and expensive machines as hereinafter more fully set forth,pointed out in my claims and illustrated in the accompanying drawings,in which-;-

Fig. 7 shows a etail plan view,illustrating the shaft of the adding wheels, and the spacing barsthereon for separating the adding -WhG8lS. Fig.- 8 shows an enlargeddetail view through a part of the machine frame adjacent to the shaft ofthe adding wheels, showing some of the adding wheels in se tion, andsome in elevation, and illustrating from which numbers are printed, andthe dotted lines show the positions of these printing hammers adjacentto the adding wheels from which the totals are taken. Fig. 9 shows aside view illustratin the device for normally locking the shaft of theadding wheels, and. for releasing and turning the said shaft forclearing the adding wheels and returning them to normal position. Fig.10 shows a rear elevation of the entire machine with part of the paperroller broken away. Fig. 11 shows a detail sectional View illustratingthe key bars for printing totals, and the arrangement by which adepression of one of the key bars will cause a movement of all of the)rinting hammers to the right of the key bar epressed, so that theentire-total may be printed'by a single operation. The dotted hnes inthis figure show the key bar in the fourth column depressed, and all ofthe other key bars to the right correspondingly depressed by it. Fig. 12shows a face view of the three printing wheels to the left of themachine illustrating the position of the periods on the second wheel toindicate decimal points. Fig. 13 shows a detail perspective view of themechanism for operating the printing hammers, and for shiftlng theearriage'that supports the printing hammers and paper holding devices.Fig. 14 shows a detail view illustrating the mechanism for clearing theadding wheels and returning them to normal position, the pawl beingshown in position for permitting the pin on the adding wheel to pass it.Fig. 15 shows a similar view with the pawl in position to engage andstop the pin on the addin wheel. Fig. 16 shows a detail plan view of t eshaft for supporting the said pawls, and also showing a number of pawlsin osition on said shaft. Fig. 17 shows a detai lan view illustratingthe lever for shifting t 10 ribbon supin the frame is a shaft 11 forsupporting the ievers of the printing segments. I have provided one of tese levers for each column of key bars. The body portion of the lever isindicated by the numeral 12, and normally inclines upwardly at its frontend, its rear end bein provided with a segmental printing arm 13, havingon its front face a series of cogteeth 14, and having on its outer facea series of type 15, the upper type having the numeral 0 the next thenumeral l and so on. ,The rear end of the lever 12 is nor mally helddownwardly by means of the spring 1.6.; Obviously, if the forward end oft e lever is moved down a short distance, the second type from the topof the segmental bar 13 will be moved to printing position, and if moveddown to its lower limit, the last type of the segmental bar 13 will bemoved to printing position. I have provided for operating these leversthe required distance by means of a series of keybars for each of thelevers 12. These key bars are each indicated by the numeral 17 and areslidingly mounted inthe top of theframe and in a supporting bar 18. Eachis normally held to its upper limit by means of a spring 19, and theshoulder 20 is formed on each as clearly shown in Fi 19.

The first key bar indicated by the numeral 21 is designed to print thenumeral 0, and is not provided with any notch, and does not affect thelever 12: The adjoining key bar has its bar 13 to the distance requiredfor bringing the second type into printing position. The shoulders 20are arranged in different position on all of the key bars 17 so thateach when moved to its lower limit will operate the lever 12 in suchmanner as to bring the corresponding type to printing position.

I have provided for printing from the type on the segmental bars 13 asfollows: Mounted beneath the sliding key bars is a crank shaft 22,having crank arms in position to be engaged by the key bars 17 whendepressed. ()n the rear end of each of the crank shafts 22 is a crankarm 24. The numeral 25 indicates a carriage slidingly riage 25 is aseries of supports 31, to each of which I have pivoted a printing hammer32. This hammer is normally held away from the type by means of thespring Each hammer is formed'witliia slot 34 into which the crank shaft24 is.placed. By this construction, a depression of any one of the keys17, or the he 21, will operate to first set the type bearing segments 13to proper position, andwill then operate the printing hammers. The crankarms 24 are made long enough so that the carriage 25 may be shiftedtransversely of the machine to the required amount without affecting theoperation of the rintinghammen' '1 1e ribbon support comprises twobrackets 35, mounted at opposite sides of the machine framc,andcontaining the shaft 36, having a ribbon spool 37 at its top, and abevel pinion 38 at its lower end. These brackets 35 are fixed to theshafts 3S) and 40,

which are slidingly mounted in the frame,

and I have provided for sliding the shafts as follows: Pivotc'd to oneside of the machine frame is a lever 41, connected by a rod 42 with abell crank lever 43, fulerumed to a bracket 44, on one of the uprights26. The other end of the bell crank lever is connected to thebrackets'35, and when the lever 41 is depressed, the shafts 3i) and 40,together with the brackets 35, are shifted transversely of. the machine.On each end ofthe roller 28, is a ratchet wheel 45, having projectingoutwardly from its outer surface two teeth 46. These teeth aredesignedto engage the bevel pinions 38, and when one of said ratchetwheels is in position in engagement with one of the bevel inions 38, itwill be rotated as the paporis at vanced, andwill turn the bevel pimon38 two spaces during each revolution of the ratchet wheel. This will besuiiicient to advance the ribbon spools the desired amount, and when thelever 41 is operated in any direction to shift the ribbon device, themotion of the ribbon winding spools will be reversed.

I have provided for advancing the paper roll 28 as follows: Fulcrumed tothe machine frame at one side is a lever 47 having pivoted to its lowerend a rod 48, provided with a tooth 49. This tooth is normally inengagement with the ratchet wheel 45, and is so arranged that a movementof the lever 47 will turn the paper roll 28 the proper distance forspacing apart the lines in a column of figures.

I have provided means for carrying totals from one type bearingsegmental bar 13 to the others, and forvisibly indicating to the oorator at all times as follows: Hounted in t 10 machine frame 10 is ashaft 50 having a I have arranged a series of nlunerals 54, alsoconsecutively arranged from U to 9, so disposed with relation to theother numerals 53, that when the numeral 1 on one wheel is in printingposition, that is adjacent to the a'mmer 32, the numeral 1 of the series54 Formed on of rate et teeth, 56. Rotatably mounted on the hub of eachof the wheels 52, is a wheel 57, having cog teeth formed thereon, and

the'teeth 58. .52 is a splring actuated pawl 60, designed to ratchetteeth 59 formed thereon, adjacent to Carried by each of the wheelsengage t e adjacent set of ratchet teeth 59. Between each wheel 52 andthe adjacent wheel 57, is a spacing washer 61, held against rotation onthe shaft 50 by means of the arms 62 resting upon the support 63, asclearly shown in Fig. 7.

Formed within each of the wheels 52 is a circular recess 64,surrounding'the shaft 50.

with the shaft 50.

In this recess is a lug 65, and fixed to the shaft 50 is a pin 66. Thispin. 66 is normally in such position that the whcel-52 may freely rotatewithout having the pin 66 engage the However, when the shaft 50 is thespring 51, the pin 66 will engage the lug 65, and thus cause the wheel52 to rotate I have provided for manually moving the shaft 50, and forrotating it, as follows: Formed on the frame 10 is a clutch member 67surrounding the shaft 50.

" Fixed to the end of the shaft is a hand wheel 68., having a clutchmember 69 formed thereon to coaet with the clutch member 67. By .meansof this mechanism, if it is desired to move ,all of the wheels 52 byhand, the operator grasps the hand wheel 68 and pulls it out ofengagement with the clutch memher 67, thus bringing allof the pins 66into engagement with the lugs 65. He then turns the hand wheel 68, andin this way moves all of the wheels 52. In this connection, it is to beunderstood that thelugs 65 are so arranged within the wheels 52, thatwhen the shaft 50. has been turned a com- 'plete revolution, with theclutch members 67 and 69 out of engagement, all of the wheels 52 will bemoved to position with the numerale 0, all in printing position, and inposition Where they will be visible through the openings 55, so that inthis way the machine may be cleared at any time.

I have provided means for carrying totals from one wheel to the next asfollows: On the rear side of each of the wheels 52, is, a laterallyprojecting pin 70. Pivoted to the forwar end of each of the arms 62, isa lever 71, having pivoted to its upper end an arm 72, formed with aninclined shoulder 73, and inclined shoulder 74. Pivotally mounted on topof the arm 72 is a spring actuated pawl 75, normally held by its springin'engagement with the ratchet teeth 56 of the adjacent wheel 52, to theleft. Arranged below thearm 72 is a shaft 76, supported by the machineframe, and carrying a series of pawls 77, each of which has two lateralpro: {)ections 78 and 79 on one side, with a space etween them. The 0)eration of this carrying mechanism is-as f0 lows: When the'first Wheelto the right has been moved to posi-- tion, with. the numeral 9 thereonin its printing ]position and visible through. the opening in t. 1e topof the frame, where the pin 70 is in position in engagement with theshoulder 74 of the pawl 72, as clearly shown in Fig. 2'. Then when thewheel 52 is moved one type space further, the pin 70 will throw the arm72 toward the front of the machine, and the pawl connected to the arm 72will cause the next wheel 52 to thecleft. to be moved one type space. Assoon as the arm 72 has been operated to move the adjacent wheel 52 onetype space as above described, the inclined shoulder 73 of the arm 72,will strike upon the shaft 76, and thus elevate the arm 72 out of thepath of the pin 70, as shown in Fig. 14, so that if the wheel 52 to theright should have been moved more than one type space, the wheel to theleft will be moved only one type space and no fartherj A in clearing upthe machine by turning the hand wheel 68 as before describedwthe pins 70would be stopped in position ih engagement with the shoulder 74 of thetypewheels 52, and in order to start the machine in operation after ithas been cleared, it is necessary that thesepins 70 be in position pastthe shouldcrs 74 of the pawl 72. To )rovide for this actuatedpositioning of the wheels 52, I have placed on the shaft 76, a crank arm80, de signed to enter a notch 8'1 formed in a disk 81, fixed to the hubof the hand wheel 68, as clearly shown in Figs. 3 and 9. as beforedescribed, are fixed to this shaft 76, and they are so arranged'thatwhen the crank arm is resting in the notch 81 as shown in Fig. 3, thearms 77 will stand in the position shown in Fig. 14, and when they arein this position, the pins 70 may be passed through )etween the ugs 7Sand 79 of the arms 77, but when. the hand wheel 68 is turned, then therear end of the crank arm 80 will be elevated, thus bringing the arms 77to the posi tion shown in Fig. 15, where the pins 70 will strike againstthe lugs 79, andthus all of the wheels 52 will be stopped inthisposition, which (position is such that the pins 70 will be beyon theshoulders 74 of the arms72, so that when startingto operate the machineafter it has been cleared, the pins 70. will not engage the shoulders74,:until after the wheels 52 have made a complete revolution,

The arms 77,

it being understood that as soon as the hand wheel 68 has com leted.its, revolution, the,

a m 7 7 willlagein. rep to the n s fii nshawn in Fig. 14, where the pins70 will not inter.- fere, or engage with the arms 72, or the lugsthereon. In this connection, it is to be understood that when all of thewheels 52 have been turned to position, with the pins 7 thereon restingagainst the lugs 79 as shown in Fi 15, all of the numerals 0 on theadding whee s will be in printing position, and be visible through theopenings inthe frame. The lugs 78 are for the purpose of engaging thelugs 73 on the arm 72, and holding the arm 72 in an elevated position,as shown in Fig. 15, so that the lugs 74'will not stand in the path ofthe pins 70.

From the foregoing description it will he understood that the printingof numerals in the first instance will bedone from the type on thesegmental bars 13. I have provided means for printing totals at any timedirect from the wheels 52, as follows: I have described heretofore, themovable carriage on which the printing hammers 32 are mounted. Thesehammers normally stand in position to irint from the type on thesegmental bars 13,

mt they may be shifted as shown by dotted lines ,in Fig. 8, topositiongfor printing from the type wheels 52. This mechanism eomprisesa key bar 82 in each column of key )tLI'S, normally held by a spring inthe same way as the key bar 17, and each iirovided near their lower endwith a lug 83. i ounted adjacent to the lug 83 is a shaft 84 having aforwardly projecting crank arm 85, to which a cross rod 86 is attached.This rod is in the path of the lugs 83 so that when the key 82-isdepressed, the lug 83 will engage the rod 84 and push it downwardly.Fixed to the shaft 84 is a rod 87 connected to the crank arm 88 and ashaft 89, the lower end of which is provided with an arm 90 to enter anotch 91, formed in the sliding carriage 25, as shown in Fig. 18. inthis way, the first effect of a downward movement of any of the key bars82, will be to shift the carriage to position with the hammers32'opposite to the wheels 52. The next effect of a downwardly movementof any of these key bars 82, will be to have their lower ends strikeupon the crank arms 23, and thus actuate the printing hammers- The saidkey bars are shown in this position in Fig. 11, by dotted lines. I havealso provided means whereby the entire total mav be printed by thedepression ofa single key, as follows: On each of the key bars, 82except the first one to the right, I have formed a lateral extension 92,to overlap a pin 93 formed on the adjacent key board to the right. Bythis means, and assuming that the total sum to be printed was in fourfigures, then theoperator would depress the key bar 82 in the fourthrow, and the extension 92 would engage the pins 93 and thus depress allfour of the key barsto the right, as shown by dotted lines in Fig. 11.

In pra'ictical use, and assuming that the seams machine is in its normalposition, and assuming that the number 5555 is to be printed, then theoperator depresses the key bearing the numeral 5, in the fourth column,then the key bearing the numeral in the third column, then in thesecond, and then in the first; The printing will be done direct from thesegmental bars 13, and the adding wheels 52 will have no part in theoperation, except that they will each be moved by the pawls so that thenumerals thereon will stand in position with the numerals 5 on the firstfour Wheels in printing position, andwith the numerals 5 of the samewheels of the set shown in black in Fig. 8, ap earing through theopenings in the top of t 1e frame; Then the operator depresses the lever47, thus advane ing the paper one line space, thcn the operator proceedsto print the next number in the same way. Assuming that the secondnumber to be printed contains the last numeral of a value of five ormore figures, then the printing is all done from the segmental bars inthe same way as before described, but the carrying mechanism will causethe second adding wheel to the right to be moved one type space, thuscarrying ten from the first wheel to the right, to the second wheel. Theoperator proceeds in this Way until the column of figures to be addedhas been completed, then'assuming that it is desired to print the total,and the total number comprises five figures, he then depresses the fifthone of the key bars 82, thus shifting the carriage to bring the printinghammers in operative position with relation to the adding Wheels, andimmediately thereafter operat ing the printing hammers jointly to printthe total.- Assuming that, it is desired to return all of the addingwheels to normal position with the numerals O appearing in printingposition through the openings in the frame, then the hand wheel 68 isgrasped and moved to release the clutch members 67, and then rotated acomplete revolution, this will have the effect of causing all of thepins 66 to engage the lugs 65,.and thus move all of the adding wheels tothe desired point, and at the same time it will operate the crank. arm80 in such manner as to bring the arms 77 into the path of the pins 70,thus positively stopping all of the adding wheels in the properposition, and at the same time allowing these pins to pass the shoulders74 of the arm 72 so that the machine will be in position or starting anew operation.
